I ran out of space on my practice pad, but then I remembered I had this piece hanging sneakily in my closet.
So I found a chunk of backing fabric and used it to practice free-motion squiggles instead!
Alas my thread is black and it's hard to see exactly what I did.
Squiggles are a challenge! I didn't expect that!
But in the end it turned out alright. I've never made a quilted pillow before. I put together a back to it last night--just a trimmed-up fat quarter and a contrasting border--so I guess I'll use the front and back as free-motion practice pads and figure out how it gets put together later. There's whole groups devoted to pillows, after all :-)
